从web.config获取价值到XSLT文件中 [英] Get value from web.config into XSLT file

问题描述

我的Web.config中有一些要在XSLT文件中访问的值.我该怎么办?

I have some values in my web.config that I want to access in my XSLT file. How do I do that?

我这样做是为了将配置文件加载到我的XSLT中:

I have done this to load the config file in my XSLT:

<xsl:variable name="config" select="document('..//Website//web.config')"/>

<p><xsl:value-of select="$config//appSettings/add[@key='Test']/@value"/>
</p>

在此之后，我被卡住了-什么也没渲染.

After this I am stuck - nothing gets rendered.

好的.我做了一些更改.我尝试使用一个单独的XML文件，并且能够从该文件的变量中获取值.

Ok.I have done some changes.I have tried using a separate XML file and i am able to get value from the file in my variable.

    <xsl:apply-templates select="document('TestXML.xml')/test/Tag1">

    </xsl:apply-templates>

    <xsl:template match="Tag1">
      <xsl:choose>
       <xsl:when test="@sName='myTest'">
        <span>
          <xsl:value-of select="@TestId" />
        </span>
      </xsl:when>
    </xsl:choose>    
  </xsl:template>

我仍然感到困惑，即在读取web.config文件(这是一个xml文件)时，我得到了一个空变量，但是对于纯.xml文件，我在我的变量中得到了一个值.

I am still confused that while reading the web.config file(which is an xml file), i get an empty variable, but for a pure .xml file i get a value in my variable.

我的Test.XML是这个

my Test.XML is this

<?xml version="1.0"?>
<test>
  <Tag1 sName="myTest" TestId="328,329">
  </Tag1>

</test>

请帮助我如何使用<appsettings>部分下的值的Web.config文件.

Please help me as to how could i work with a Web.config file with values under <appsettings> section.

推荐答案

document()函数应接收有效的URI方案. XPath中使用双斜杠//，但在URI中不是有效的路径分隔符.如果您的web.config文件位于Website目录中，该目录是XSLT所在目录的同级文件，则语法应为:

The document() function should receive a valid URI scheme. Double-slashes // are used in XPath but are not valid path separators in an URI. If your web.config file is in the Website directory which is a sibling of the directory where your XSLT is located, the syntax should be:

<xsl:variable name="config" select="document('../Website/web.config')"/>

假设样式表的其余部分正确无误，并且web.config中XML的结构与之匹配，则value-of中的XPath表达式应该可以工作.

Assuming the rest of your stylesheet is correct, the XPath expression in the value-of should work if the structure of the XML inside your web.config matches it.
